You can use the terms "and" & "or" in your search; "or" phrases are resolved
first, then the "and" phrases. For example, searching for "black hole and
galaxy or universe" will find articles that have the phrase "black hole" in them
and also have either "galaxy" or "universe" in them. Please note that other
search syntax like quote marks, hyphens, etc. are not currently supported.

When you view web pages with matches to your search, the terms you searched for will be highlighted in yellow.
